I tried this when I was working on MR !7698, and it didn't have much affect back then. Maybe I've added more stuff to my fossil-db? Gfx12 platforms (Tiger Lake and DG2) are unaffected because the POW instruction was removed. shader-db: Ice Lake and Skylake had similar results. (Ice Lake shown) total instructions in shared programs: 20301933 -> 20301900 (<.01%) instructions in affected programs: 9077 -> 9044 (-0.36%) helped: 33 / HURT: 0 total cycles in shared programs: 842797624 -> 842799471 (<.01%) cycles in affected programs: 1361911 -> 1363758 (0.14%) helped: 35 / HURT: 111 LOST: 0 GAINED: 9 fossil-db: Ice Lake and Skylake had similar results.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
